Retractable Lances

A retractable lance allows you to withdraw your nozzle, isolate it from the process, and then remove it completely for servicing without taking your process offline. Once the industrial nozzle is serviced, cleaned, or inspected; simply reattach it to the system, open the isolation valve, and insert it back into the process. This is often a critical requirement for petrochemical facilities where process outages are costly.

For example, certain applications involved in the production of petroleum contain particles that are very erosive. The ability to remove the nozzle for refit while keeping the process online offers a tremendous cost savings.

Spray Nozzle Engineering, the exclusive supplier of BETE industrial nozzles in Australia and New Zealand, offers a robust retraction mechanism that effortlessly moves the lance from extended to inserted and back. A simple cordless drill is all that is required to power the unit, making this design a favourite with maintenance crews. The mechanism is flexible in its configuration; allowing alternate electric, pneumatic, or hydraulic power sources to drive the unit.
